The vinterior of the carhnreter 1s dividedinto two, compartments by .& yerticel part1- ortion-to' the quantity of' explosive charge a lowed to pass through from the hub 26 ofthecap 25 is tion 40;Jthecontou1' of which will be seen on 'refeienoefito Fig. 2. The larger compartgasolene reservoir, while the sinalleroomfimrtmentel forms sport or-pes the partition is arranged concentric the-cirquler wall of which the airasses from port -j the casing and is slightly spaced therefrom to form an annular recess into valve 31 may pass.

In alinement with the vertical center of the port 12 is a gasolenefeed pipe 44 that is arranged in an arcuate line following exactly the curvature of the gate valve, and this pipe is provided with 'a number of perforations which face the gate valve and which are controlled by the latter, so that as the gate valve moves to open position the perforations will be successively uncovered and the number of perforations exposed will be in exact proportion to the extent to which the valve is o posits the constantly opened t 'eplort 12, so that a charge can a ways pass to" t opened. This gasolene pipe is supported by a tube e5 which leads from the port or passage 23, and the level of liquid maintalned in the larger compartment of the carbureter is suchthat the pipe will be constantly fil1ed.-

The end opening of the gasolene pipe 44 is ortion of e cy'linder of the engine for starting purposes, and this, without the necessity of openingthe valve and flooding the cylinder,

as ls'iieual in the majority of devices of this "in o eration, the lever 36 is moved either -maiiua' 1y "or automatically, and as the gate valve'31is opened, the perforations in the pi eer are successively uncovered, and as a arger quantity of air passes through theort' 12, a'lar ger number of perforations will e openedto'su plfy gasolene for carbureting the air, and at t e same time the needle valve will-be opened to a greater extent to furnish the increased quantity of gasolene.

'It will be-seen that the qualit of the charge is. uniform no matter what t e quantityr'hay be, and the propgrtions of gasolene and are exact without regard to change ad of the engine.

"In a carburetor, a casing havin an air epro'vi'ded with ports in bot alve controlling the discharge ort, s11 ge pg s facing the gate valve and under control of said gate valve, a second valve cont fllingthe quantity of fuel passing into the-supply pipe, a'ndmeans for connecting the two valves for mutual movement.
